Brand: HiDes Technology
SKU: HV-310J/JH

HDMI/CVBS to ISDB-T/ISDB-Tb Modulator

170–1350 MHz

HV-310 is the most cost-effective solution to transmit long range HD video for FPV application with digital TV technology. The video input source from either HDMI/DVI or composite (CVBS) is encoded in H.264 streams, modulated with the open industrial standard EN 300-744 DVB-T/ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb, and then transmitted over cable or air. All DVB-T/ISDB-T/ISDB-Tb compliant receivers, including SetTopBox, Digital TV, PC/NB USB DTV dongle, or DTV capture card can receive, and watch the video from a HV-310 via the standard coaxial cable or antenna. HV-310E supports EN 300-744 DVB-T modulation while HV-310J supports ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb modulation. (Note: HV-310J supports only H.264 encoding while old Japan ISDB-T TV cannot support it.) HV-310 supports 170MHz~1350MHz (excluding 950~1090MHz) band transmission. With embedded high power amplifier design, the RF output power can reach up to +15dBm for the frequency range 474~930MHz. HV-310EH/HV-310JH is special edition with high gain design for 1.2G band, which supports higher output power in 1.2G band while lower in 170-950MHz band.

Features

01 High Performance Wide Frequency Range Support — Direct digital conversion to 170~1350MHz (excluding 950~1090MHz) for excellent signal quality. Professional grade modulation error rate (MER). With embedded high power amplifier design, the RF output power can reach up to +15dBm for the frequency range 474~930MHz.
02 Low Cost HD Video Distribution — Compliant to existing HD TV sets, no extra adapter required, and no restriction on the number of receivers. All the peripherals like splitter, amplifier, connector…etc are the same as those for regular TV. In DVB-T mode, 1MHz~8MHz Bandwidth options are supported.
03 Versatile video inputs — Support HDMI/DVI and composite (CVBS) video input.
04 Easy to Configure — Channel number can be configured with the IR RC easily. More advanced configurations can be set from an external host like PC/NB thru serial port interface.
05 Robust, Reliable and Long Distance — Easily transmit 1080p video over a single 3C2V/RG59 cable for at least 500 meters long without adding any repeater. For wireless applications, the line of sight transmission distance may reach 50~100 meters at 0dBm RF radiation power and up to several kilo meters at 30 dBm with an external PA. The real distance depends on the antenna design and receiver quality. Differential RF output is also available for RF signal distribution with twisted pairs (telephone or Ethernet RJ-45) instead of heavy coaxial cables.
06 Daisy-chain Connection (Bus-Topology) — Multiple HV-310’s with different channel configurations can share a single cable. It can dramatically reduce the cable deployment cost and effort.
07 Real time protocol and Low latency — No frame drop in QEF (Quasi-Error-Free) condition, and low transmission latency.
